AT ENEYJ WILLIAM NEIGEL, OF FLANDR'EAU, SOUTH-I SI-IGCK-LOADER.

Application filed January 3, 1913.

To all w/mm it may concern:

Be it known that I, lViLLr-wa Wmonn residing at Flandreau, in the countyof Hood and State of South Dakota, have inventcd a new and ImprovedShock-Loader,

of which the followingis a specification.

My invention which relates to improvements in harvesting machinerygenerally, more particularly has reference to shock loading machines, ofthat type in which the shock gatheringelements are pushed into the shockand caused to engage the shock in able conveying means that delivers thepathered shock into a wagon or deposits it at the desired point.

The primary object of my invention is to provide a shock. loading;machine of the general type referred to of a simple and inexpensiveconstruction, and in which the parts are especially designed forgathering and loading, a new shocl: as a prior gathered shock is beingdischarged from the machine.

Another object of my invention is to provide certain improvements inshock loaders of the type stated in-which the parts are so arranged thatthe operation of setting into action the shock delivering; means automatically effected as a gathering means is pushed into engagement withthe shock to be loaded; a suitable number of the said gathering meansbeing provided whereby the operation of gathering a new shocl: anddelivering a gathered shock is simultaneous, and the cooperation ofseveral connect ed mechanisms is such; that they present a compacteasily controlled and etlieient means for the purposes stated.

With other objects in viewthat will hereinafter appear myinventionembodies the novel features of construction and peculiarcombination of parts all of which will be hereinafter explained,specifically set out in the appended claims and illustrated in theaccompanying drawings, in which Figure 1 is a top plan view of myinvcn-' tion. Fig. 2 is a vertical longitudinal section thereof,takensubstantially on the line 2-2 on Fig. 1. Fig. 3 is a detailperspective view, parts being in section, of the power transmittingmeans and the automatically controlled clutch devices hereinafterreferred to. Figf e is a detail perspective view of one of the shockengaging forks. and G, 7, S and 9 are diagrammatic views S ecificationof Letters Patent.

that illustrate the different adjustments of the clutch devices thatcooperate with the ratchet drive and hereinafter more specificallyexplained. Fig. 10 is a. detail perspective view of one of the ratchetand pawl devices.

in the ractical embodiment of my invention the same includes a mainframe composed of front and rear longitudinalbeams 12, preferably squaretubing, and braced I by an end cross member 3 and intermediate 7 itubular cross beams such manner that .is delivered onto, suit- 5designates a master wheel supported by and horizontally rotatable uponone of the cross beams 4t, and held thereon. b a king bolt '6. Wheel 5has a bevel gear a that meshes with a bevel drive pinion 7 on the innerend of a. shaft or axle 8, a ground wheel 9, at the adjacent end of thesupport- 12 is driven by a pinion 13 on engine shaft 13. 1

By referring more particularly to Fig. 1,

it will be seen that: I have provided four angles to each other, andindividuallv hinged to the master wheel as at l-fl. Each fork consistsof a head bar 15 from which the tines 16 of the forks extend, and aninwardly extended lever arm 17, that is hinged at the inner end to themaster whcel5. so it, 'with the fork head, may swing in the verticalplane, The for]; head is hingedlv ioined to the outer end of the arm 17for vertical swing independent of the said arm. the rea son for whichwill presently appear, the hinge connection 18 for the arm 17 and thefork being, however, such that the fork does not drop in a plane belowthat of the arm 17' during the different adjustments thereof. At thispoint it should be stated. my mechanism includes means for automati calleffecting a vertical lift of th after it has penetrated the shoclc i putthe said fork in ing' frame, is loosely mounted in horizontalforks orshock penetrators, disposed at right moved into engagement with asupporting guide, that holds the said fork with its shock load in properposition for being antomatically conveyed to the point where r the shockis dropped onto the ofitake or disoharr in means and onto a uidewa whichthe fork continues on its return move ment, lifts the fork high enough.to clear the heads of the horses that push the machine and then lowersthe said fork into its first position ready to penetrate a new shock.For effecting the desired operations of the forks, I have provided animproved arrangement of intermittently operating drive mechanisn'iserved from the motor drive, and the said drive mechanism is best hedisks 1G and and their driving means are so timed and relatively are sooperated that the operation of lifting the fork that penetrates theshock is effected immediately after the shock is engaged, and the masterwheel rotation is produced for swinging the loaded fork around to thedelivery point which is begun just before the clutch or pawl 19 isreleased from its ratchet wheel, the operation being first to lift thefork, then swing around the filled fork as another forlr is being movedinto a. shock ing position.

so denotes a segmental guide which is in an elevated plane relatively tothe master wheel, and the said guide supports the loaded fork as isswinging from the first position around to the second position forcoacting with the shock takeoff means presefcrred to. r

L de, gnates another segmental. guide and support, concentric with themaster wheel and which includes an incline 25 on which the fork lever 17drops when the fork reaches its second position.

(fluids extends around to where the le ver arm 17 of the forks assumetheir first or penetrating position and it stops at a vertical post 26,a plurality of similar posts 29 being mounted on and movable with themaster wheel 5 and against which the roller bearings 27 on the lever arm17 travel as the said lever is raised.

Referring again to Fig. 5, 30-31 designate a pair of laterally swingabletripper arms, connected by a rod 32 to cause the arms to move togetherand normally swing in one direction by the tension of a spring noeaooa33. Tripper'arm 30 has a beveled edge 34, normally in the path ofmovement of the pawl 19, whereby when the said pawl is held inengagement with the ratchet 10, it engages the said beveled edge 34 andthereby gradually swings the arms 30 and 31 over, and since the arms 30and 3l'include fingers 3535 that normally extend over the ratchets 10-20for holding their coacting pawls 27 and 19 lifted out of engagement withthe ratchets, it follows that at a predetermined time, the finger 35 ontripper arm 31 moves from under lip 36 on pawl27 and the extent of aquarter turn thereof, since the timing of the action of the pawl 27 issuch that the trippin finger 35 engages and lifts pawl 27 out ofengagement with the ratchet 20 at each quarter turn of the master wheel.

The manner in which the pawl devices are consecutively operated andtimed to perform the functions stated isv best explained as follows :Arocking lever 10 is fulcrumed on the under side of one of the crossbeams 4 and it includes an upturned member 41 for engaging the free endof the pawl 19, it-

being normally held from the said pawl by a spring 42.

48 is a slide rod thatconnects to the free end of the lever 10 and hasits front end projected under the tines of the fork device, located atthe front or penetrating side of the machine, and its front end is benttransversely to form an abutting or head portion Flat. By reason of thearrangement of the slide rod connection and the lever connection withthe pawl 19 it follows that when the fork is at its proper position, as.

shown in Fig. 1, the correlation of pawl 19 and the disk 10 is as shownin Fig. 6, the fork being now down and at the sh0ck penetratingposition.

When the fork is pushed into the shock, the head portion 44 reg engagesthe shock and it consequently forces, rod 43 back in the direction ofthe arrow and thereby rocks the lever 40 and forces its end against thepawl 19, causing it to engage the ratchet on the shaft, the said partsbeing now in the position shown in Fig. 7, by reference to which it willalso be seen that as the pawl 19 is swung against ratchet 10 a lug19 onthe said pawl enadvance will also'be raised, a fleXible win a es a seental kee er 45 to ositively t iol d the 531 19 locke d with the disk10, to that extent of time'necessary to eifect the lifting of the forkand puttingit in position to engage the initial segmental support 23therefor. v -;1- {simple, efiicient, and quickl actuated pulley 53 andconnects with one end of a.

means for lifting the fork is diagrammatt cally shown in Figs. 3, 4, 5and 6, in which 52 indicates a flexible pull rod or chain, one end ofwhich is connected at 19" on the pawl 19.

The pullmember 52 passes under a guide tiltable lever 54., best shown inthe several diagrammatic views, and whose free end normally lies underthe arm 17 that carries thfe front fork, it being obvious, by reason ofthe peculiarmanner in which the several parts are combined, that as disk10 with pawl moves, the pull member is pulled around 'with the pawlrocking lever that raises the fork; it being understood, pawl 27-for theother disk 20 moves into operativej engagement with the said disk'20just before the lug 19 of pawl 19 moves out of the segmental guide, andso soon as it does, lip

36 on pawl 19 comes in contact with finger on tripper arm 30 and liftspawl 19 out 10f engagement with ratchet 10; pawl 19 is held'out ofengagement with ratchet, 10 by -spri'ng Ql and thereby permits the saidarm nd the pawl .19 to hang free and loosely from the said shaft 8during the subsequent operation throu hthe pawl 27 and rack 20, of themaster w unloading position.

. After a fork is loaded, it is swungaround at'right angles to the lineof shock penetration, atwhich time another fork will occupy the place ofthe former, its successive 1 advance of position being accomplished bythe-following means; at the time when one fork: at the shock penetrationposition is raised to ride upon the guide 23 the fork in nection 68being joined with lever 54 and a roller bearing 27 with the firstportion of gaid et, see Figs. 1 and 2. When dropped "to the secondposition the head 15, by reason of its hinged connection with the arm17, g-rests on an endless carrier, that consists of v sprocket chains 61driven from-a drive shaft latter having prongs 62 located in the sidebeams and which carry [sprockets 63 for receiving the lower ends .of theendless bands or belts, to which the conveyer or cross slats 64 aresecured, the Y for through the tinesof the fork. I Y 5*65 indicateshields at the-lowerends the .elevator for guiding the lower edge eel tobring the fork to the ,of the shock portions as they are combed olf thefork and for covering the sprocket connections.

The operation of the endless conveyer is continuous and it receivesmotion through an endless drive 66 that engages a sprocket wheel" 7 on astub shaft mounted in the framing and which has a bevel pinion forengaging a like bevel drive gear on the shaft 12 of the gear 12.

From the foregoing description taken with the drawings the completeconstruction, the method of the operation and the advantages of myinvention will be readily apparent to those skilled in the art.

The means shown and described present a practical embodiment of theessential features of my invention, but I wish it understood that thedetails and specific construction of the parts may be readily modifiedand varied without departing from my iIlvention and the scope of theappended claims. v
